22:35: Thank you for joining me tonight. You’ve all got 24 hours to recharge the batteries before Saturday’s Premier League action. Night!

‘WE COULD HAVE QUALIFIED’

22:30: Arsenal manager Arsene Wenger said: "Looking at the performance and the way the game went, it was the worst possible result for us, but we have to go there in a positive mood and qualify.

"Unfortunately we gave a goal away from nowhere but now we need to recover from the disappointment and prepare for the next game.

"Of course it feels like an opportunity missed. We could have qualified tonight but it didn't happen. Their keeper made a lot of saves and they showed their quality by scoring with one chance. But they couldn't score with a combination, they could only do it with a long ball, so we have to look at ourselves."

22:15: Alexandre Lacazette said: "It was a great goal to score after the ball from Jack Wilshere and I'm happy to do my job. I really want to play in the final (in his hometown of Lyon), maybe I'm the player who wants it the most in the team, but we have to work hard to achieve that."

ELSEWHERE…

22:10: Marseille secured a 2-0 victory over RB Salzburg in the other semi-final. They’ve got one foot in May’s final.

TWITTER ROUND-UP

Dave: If ever there was a match which showed the results of Arsenal's gradual decline over the last few years, that was it.

Lillian: Arsene Wenger will be heartbroken, his last chance to win a trophy or to take Arsenal to another year in Europe and he blew it

John: And there you have it, Arsenal summed up in one moment! All good, doing well then one loose ball, defensive error and disaster. This is how we always do it.

22:00: So if I’ve done my maths correctly; Arsenal requite at least one away goal in the second leg.

The problem with that? Atletico Madrid haven't conceded a goal at home since January 20...

59: So what options does Arsene Wenger have on the bench? Cech, Holding, Iwobi, Chambers, Maitland-Niles, Kolasinac, Nketiah…

58: Arsene Wenger looks irritated. It’s either because Monreal has shanked a cross straight out of play or because Diego Costa is warming up…

Ramsey wriggles past a couple of challenges but Godin arrives to halt the attack. Atletico are the kind of side who wouldn’t let the Under-10 side score against them in a charity match.

57: Atletico are trying to be too clever at the back. They keep dithering with it and Arsenal are forcing mistakes. I can feel a goal coming…

54: Ramsey goes from distance but it would have to be something pretty special to beat Oblak from that range.

51: There’s a growing sense of frustration around the Emirates as an organised Atletico starve Arsenal of chances. They look pretty comfortable with ten men, but the last 15 minutes could see fatigue set in.

48: For once the Emirates did its bit – unsettling Atletico and causing unexpected mayhem in the opening exchanges.

However, by the end of the first half Diego Simeone was not prowling quite so fiercely around the back of the directors’ box – Arsenal’s failure to find the back of the net settling his nerves more than a little.

Vrsaljko deserved red and Simeone only has himself to blame for behaviour that was bound to receive censure. But the Spanish side are still hanging on to a goalless draw away from home and belatedly they seem to have decided to get back on task.

If Arsenal don’t take advantage in the second half, they only have themselves to blame.

43:Chances are drying up fro Arsenal now. Granit Xhaka looks to address that himself by sending a 25-yard effort into orbit.

40:Bit naughty from Griezmann. He throws himself to the deck having been breathed on by Mustafi. Bit of gamesmanship from the visitors now.

38: Griezmann gets his first opportunity of the night but Ospina gathers his low 20-yard effort. While he’s still on the pitch - anything could happen.

35:Arsenal have to be more clinical. They will never have a better chance against a manager-less, ten-man Atletico Madrid.

They’ve done well to load the box and commit bodies forward but they’ve been too wasteful.

32: Close! Monreal has six goals this season and nearly adds a seventh but volleys wide from Lacazette’s flick-on.

30: Marseille are leading RB Salzburg 1-0 in the other semi-final. Former Newcastle midfielder Florian Thauvin has scored, assisted by ex-West Ham star Dimitri Payet. Letters of thanks can be sent to The Premier League, PO BOX…

19:59: Arsenal manager Arsene Wenger: "It has been very busy but I try and keep the priorities right because I live for competitions. I will try and do as well as I can for as long as I am here.

"The fans will be behind the team don’t worry about that, our home form has been very strong.

"The weight of the away goal is huge. We ideally score without conceding which has not been our strongest point that season. We have to stop them counter-attacking, keep Antoine Griezmann quiet and cope physically with Atletico."

FAREWELL TOUR…

Analysis from our reporter Uche Amako, at the Emirates Stadium.

19:56: The countdown to Arsene Wenger's exit continues tonight with his final European home match.

And after years of disappointment in Europe, the Frenchman will be desperate to leave with the Europa League trophy and subsequent Champions League football.

But to do that, Wenger will need his players to produce one of their best displays of the season against tournament favourites Atletico.

Across from Wenger on the touchline is Diego Simeone, who has been linked with his job following the excellent job he's done with the Spanish side.

19:33: With three central midfielders in Atletico's four-man midfield, a lot will depend on Angel Correa for Atletico.

The Argentine's low centre of gravity, speed and trickery poses a clear threat to Nacho Monreal.

Monreal has had his best goalscoring seasons for Arsenal but he will have to be at his best defensively to stop Correa tonight.

COSTA…

19:30: I’ve got mixed emotions about Diego Costa returning tonight.

It’s kind of nice to see the Spaniard back in London, but ‘nice’ like seeing a guy who used to punch you in the nose twice a year…

The former Chelsea striker scored three times in six games against the Gunners during his time at Stamford Bridge, including the equaliser in last season's FA Cup final which Arsenal went on to win 2-1.

The Spain international always seemed to be able to rile the Arsenal defence and was directly involved in red cards issued to Gabriel and Per Mertesacker during separate clashes between the teams.

Rules: Last European fixture for Arsene Wenger as manager against a seriously strong and talented Atletico Madrid. Ridiculously hyped for this one!

Gas: If we go out to Atletico Madrid after playing well and not rolling over, I'll be okay with it. We're good enough to beat them, but only if we defend like professionally coached defenders and give the ball to Lacazette when he asks for it.

Matty: Our fan base has so much negativity and hatred towards players it's unreal. Everyone of us fans should be behind the team no matter what happens. So let’s all get behind the team so they give everyone a night to remember.

THE PROGRAMME…

19:23: I hope whoever is in charge of puns in the Arsenal marketing team is working on something better for Arsene Wenger’s departure. Arsene Wenger also looks about 37-feet tall, which I’m alright with…
